DESCRIPTION OF THE PREFERRED EMBODIMENTS
Hereinbelow, the present invention will be described in detail with reference to the accompanying drawings and the reference numerals therein.
A door locking handle assembly of the present invention comprises a handle piece 2 which is extendibly and retractably received in a base-end portion of a casing 1 and pivoted to the casing 1 through a first cross pivot 3. The handle piece 2 is adapted to be held in its retracted position within the casing 1 by a button member 7 mounted in the casing 1.
Further, in the present invention, the button member 7 is provided with a leg plate portion 8 which extends from a rear surface of the button member 7. The leg plate portion 8 of the button member 7 is provided with an axial hole 9. On the other hand, a base plate 10 of a button unit 6 is provided with dual bearing plate portions 11 extending from a front surface of the base plate 10. Each bearing plate portion 11 of the base plate 10 is provided with an axial hole 12. A second cross pivot 13 passes through these axial holes 9, 12 so that the button member 7 is pivoted to the base plate 10 through the second cross pivot 13 and biased forward by a spring 14.
As is clear from the above description, the button unit 6 is constructed of the button member 7, the second cross pivot 13, the spring 14 and the base plate 10.
The casing 1 is provided with a space 15 in its lower portion. The space 15 of the casing 1 is adapted to receive the button unit 6 therein. The button unit 6 is received in the space 15 of the casing 1 so as to have: the button member 7 disposed forward; the base plate 10 fixed to a bottom wall 4 of the casing 1; and, opposite ends 13a of the second cross pivot 13 abut on inner surfaces of opposite side wall plate portions 5 of the casing 1 to prevent the second cross pivot 13 from dropping from the button unit 6.
In operation, when the button member 7 is depressed in a condition shown in FIG. 3, the button member 7 swings on the second cross pivot 13 counterclockwise to permit the handle piece 2 to swing on the first cross pivot 3 clockwise, so that the handle piece 2 projects forward. The button member 7 is biased by the spring 14 forward. Consequently, when the handle piece 2 is swung counterclockwise to return to its locked position, the button member 7 automatically returns to its locked position in which the button member 7 locks the handle piece 2 to the button unit 6.
Since it is necessary for the second cross pivot 13 to pass through the axial holes 9, 12, it is also necessary for the second cross pivot 13 to have its length be equal to a width of the space 15 of the casing 1, whereby the pivot 13 has its opposite ends abut on inner surfaces of opposite side wall plate portions 5 of the casing 1 to prevent the second cross pivot 13 from axially moving relative to the casing 1. Consequently, even when the pivot 13 is not fixed to the casing 1, there is no fear that the pivot 13 drops from the axial holes 9, 12.
In the embodiment of the present invention shown in FIGS. 1 to 5, the handle piece 2 has its upper-end portion pivoted to the casing 1 through the first cross pivot 3. The cross pivot 3 has its opposite ends staked so as to be fixedly mounted in the casing 1. The handle piece 2 is biased clockwise by a coil spring 18, and is provided with a driving projection element 16 which extends from a rear surface of the handle piece 2. The driving projection element 16 of the handle piece 2 passes through a passage hole 17 of a rear surface of the casing 1 so as to be extensible and retractable relative to the casing 1, and is operated to drive a locking member (not shown).
Further, in the present invention, by inserting the second cross pivot 13 into the axial hole 9 of the push button member 7 and the axial holes 12 of the base plate 10, the button unit 6 is assembled. The button unit 6 is inserted in the space 15 of the casing 1 from the rear of the casing 1 through a rear opening of the casing 1 and mounted therein. After completion of mounting of the button unit 6 in the space 15 of the casing 1, a button-unit mounting portion 1a of the bottom wall 4 of the casing 1 is staked so that the button unit 6 is fixedly mounted in the casing 1.
In another embodiment of the door locking handle assembly of the present invention shown in FIG. 6, the handle piece 2 is pivoted to a locking shaft 2a through the first cross pivot 3. When a user wants to unlock the handle assembly, it is necessary to depress the button member 7. When the button member 7 is depressed, the handle piece 2 is permitted to swing clockwise on the first cross pivot 3 under the influence of a resilient force exerted by the spring 18. As a result, the handle piece 2 extends outward. The handle piece 2 thus extended outward is gripped by the user and laterally swung by him on the locking shaft 2a in a predetermined direction, so as to unlock the door locking handle assembly.
When the button unit 6 is mounted in the space 15 of the casing 1, the button unit 6 is inserted into the space 15 of the casing 1 from a front side of the space 15 so that the button member 7 is disposed forward. On the other hand, a rear surface of the base plate 10 is fixed to the bottom wall 4 of the casing 1 by fastening means such as screws 19 so that the button unit 6 is fixedly mounted in the casing 1.
In the door locking handle assembly of the present invention having the above construction: the second cross pivot 13 passes through the axial hole 9 of the leg plate portion 8 of the button member 7 and the axial hole 12 of the bearing plate portion 11 of the base plate 10, so that the button member 7 is pivoted to the base plate 10 through the second cross pivot 13 and biased forward by the spring 14; the button unit 6 is received in the space 15 of the casing 1 so as to have the button member 7 disposed forward; the base plate 10 of the button unit 6 is fixed to the bottom wall 4 of the casing 1; and, the second cross pivot 13 has its opposite ends 13a abut on the inner surfaces of the opposite side wall plate portions 5 of the casing 1, which eliminates the need for the staking process of the opposite ends 13a of the second cross pivot 13, in which staking process the pivot 13 is axially pressed; whereby there is no fear that the second cross pivot 13 buckles and deflects in assembling, which ensures the smooth swinging action of the button member 7 in operation.
